Sample rate LED blinking

[olloy]

Hello.
First of all sorry for bad english.

I have a MOTU 828 mkII (FW edition)

Some time ago it working well, with windows xp, and cardbus PCMCIA installed.
After few weeks some problem has occured after i change cardbus.

When i connect the firewire cable, sample rate LED starts lighting, and nothing works.
MOTU doesnt response on any knob pushed. Windows write "no motu device found"
Then i try to use first cardbus adapter. DOESNT WORK.

I'm trying different cables, different cardbus, reinstalling the drivers.
Nothing helps.

Tomorrow will try to use my 828 on friend's PC, he has a UltraLite.

If someone can help me, or just tell me where i can find solving the problem, please answer.

Thank you.
